Fe(BF4)2·6H2O/2,6-pyridinedicarboxylic acid catalysed nitrosation of a wide variety of substituted styrenes has been developed in the presence of t-BuONO/NaBH4 under H2 pressure (10 bar) in MeOH-H2O (5 : 1) to afford corresponding oximes in good to excellent yields.

Oxidative transformations of the aldehydes, ketones, and their azomethine derivatives such as hydrazones, Schiff bases, azines, and oximes are presented and discussed. The oxidants used have been hydrogen peroxide in the presence of selenium compounds as catalysts, peroxycarboxylic acids, and eerie ammonium nitrate. Some of reported reactions have practical value in the synthesis of phenols, es...

Covalent side-chain cross-linking has been shown to be a viable strategy to control peptide folding. We report here that an oxime side-chain linkage can elicit α-helical folds from peptides in aqueous solution. The bio-orthogonal bridge is formed rapidly under neutral buffered conditions, and the resulting cyclic oximes are capable of dynamic covalent exchange.

Reduction of oxi me fu nctionality to amine is an important synthetic transformation . As ox imes are stable derivatives of carbonyl compounds, subsequent reduction to amines is an attractive two-step procedure for reductive ami nation . Red uction of oximes to amines can be performed by hydride reducing agents or by catalytic hydrogenation.' Among hydride reducing agents, lithium aluminium hyd...

We are evaluating a facilitative transport strategy to move oximes across the blood brain barrier (BBB) to reactivate inhibited brain acetylcholinesterase (AChE). We selected glucose (Glc) transporters (GLUT) for this purpose as these transporters are highly represented in the BBB. Glc conjugates have successfully moved drugs across the BBB and previous work has shown that Glc-oximes (sugar-oxi...
